-** Action stamps
-I don't know any function to
-
-1. generate them from a Git commit, a *vc-change-log* buffer…
-2. convert them back to a Git commit, a *vc-diff* buffer…
-
-They can almost be generated with:
-
-#+BEGIN_SRC sh
-git show --no-patch              \
-         --date=format:"%FT%T%z" \
-         --format=format:"%ad!%ae"
-#+END_SRC
-
-Except that [[https://tools.ietf.org/html/rfc3339][RFC3339]] says:
-
-#+BEGIN_QUOTE
-   time-numoffset  = ("+" / "-") time-hour ":" time-minute
-#+END_QUOTE
-
-While ~%z~ yields "+hhmm" or "-hhmm".  Also [[http://esr.ibiblio.org/?p=3872][ESR wants Zulu time]].

-This monstrosity does the job:
-#+begin_src elisp
-(defun my/revision-at-point ()
-  (cond
-   ;; TODO: add vc support.
-   ((derived-mode-p 'magit-mode)
-    (magit-branch-or-commit-at-point))))
-
-(eval-when-compile
-  ;; Load rx's pcase pattern.
-  (require 'rx))
-
-(defun my/action-stamp-at-point (rev)
-  (interactive
-   (list
-    (let* ((rev (my/revision-at-point))
-           (prompt (if rev (format "Revision? (%s) " rev) "Revision? ")))
-      (read-string prompt nil nil rev))))
-  (let* ((cmd "git show --no-patch --date=unix --format='%ad!%ae'")
-         (git-info (shell-command-to-string (format "%s %s" cmd rev))))
-    (pcase git-info
-      ((rx (let timestamp-str (+ digit))
-           "!"
-           (let mail (+ anychar))
-           "\n")
-       (let* ((timestamp (string-to-number timestamp-str))
-              (date (format-time-string "%FT%TZ" timestamp t))
-              (action-stamp (format "%s!%s" date mail)))
-         (kill-new action-stamp)
-         (message action-stamp))))))

-ESR's =git stamp= alias in [[https://gitlab.com/esr/reposurgeon/-/blob/4.5/reposurgeon-git-aliases][reposurgeon]]:
-#+begin_src conf
-	# git stamp <commit-ish> - print a reposurgeon-style action stamp
-	# This always goes to the committer. It would be better to look at thwe author
-	# timestamp first and fall back to commmitter, because the author stamp because 
-	# doesn't change when patches  are replayed onto a repository, while the commit
-	# stamp will.

-This alias seems to confirm my feeling that Zulu time is not worth
-bothering with: ISO 8601 is just as machine-parseable, and the
-timezone bit actually conveys meaning to a human reader.
